WILLIAM J. MlliLiilt, Ol" (.Ul l lEYYlLLifi, KANSAS.

Application tiled Fehrnzn v To all whom it may concern. l Be it lcnown that l, WiLLnu J. Mitten. I. a citizen of the United States, and a resident of Coli'eyville, in the county of Montgomery and State of Kansas, have invented rertnin new and useful .lniprovenzt-uits in Molds, ol

My invention is an. iniproveziient in ntolds for glass and ther articles, and is especially 1 designed for use on glass molds, and consi. .1 in certain novel constructions and combine j tions of parts as Will he hereinafter descrihed and claimed. l

In tle drawings, Figure 1 is at side view, l and Fig. 2 a horizontal section on about the line f3'--2 of an apparatus embodying my invention. Fig.3 :1 vertical cross-section on about the line 3*3 of Fig. 1. Fig. -l is n detail side view of the slide. 5 is u. dotail View slnnving the tracks-or hearings on the mold sections integral therewith.

By my invention, 1 provide a novel construction for ei'l'ecting results secured by it somewhat ditierent construction illustrated in a, separate application for patent executed by me of even date herewith, and the present invention relates to the particular menus herein disclosed for locking the mold section." closed by the operation oi the loc ing device which is movable past the dead center oi the mold, such locking device being in the constructi on herein shown a yoke, as illustrated in the drawings. The molds of modern glass n-inchines must he opened, closed and securely locked, us each article is mode, and the speed. of the operation is governed to a inold cnn'h opened and closed.

In the construction shown, the mold formed oi sections A which ztrepivoted nt ii, the pintle B extending down into the base (has shown in Fig. 'l. The nold sections are provided on their outer sides with rircutnterentiztlly extending trot-its or hearings 1) upon which engage the ends ol' the yo 0 E. in l g. 2 the ll'zit' n'b or hearings l) are shown mode separate [rose the hold swi secured thereto, while in Fig. :3, l

illustrate such ports integral with the mold 1 sections. i'lnnliestly, they may he made: separate or integral as desired, and these tracks or hearings lorm snrl'i ce-i upon which 0 wrote the arms oi the yoliol This \'()l-'.0 ll) w ten advanced to the position shown in Fig. 1 will close and lock the mold sections by the engagement of the yoke with the snidv sec- 1 MOLD.

tions. as shown in lull lines Fig. 2, and when the \'o"-'c is retracted to the dotted line position in. Fig. 2. the yolc arms will open the mold sections by the construction shown.

lly preference to relieve the hearing ol the yoke nrms upon the mold sections, the snid nrn'is are provided with rollers e, and those rollers when the yoke is retracted engage upon the inner surlnce ol' the hnrs l secured to the mold sections and open the mold, as indicated in dotted lines Fig. 2. These hers l nre secured zit their'rcnr ends F to their respertive mold sections and are free at their forward ends and prelerz'ihly operate through slots 1 formed longitudinally in the arms ol the yoke so the snid lnu's l will not interfere with the :nlvnneing movement of the yoke arms and yet will he in position to he engaged on their inner sides hy the rollers a when the yoke is retrzn-ted.

The yoke is advanced and re rut-ted prelernhly hy the construction shown and comprising a slide or plunger G slotted longitudinull zit til in its front end and fitting within the shank of the yoke and hnving {LI its rear end it pin (l guided through on opening in tin rein end ol' the yoke slinnli. This slide U GI\Cilcl()(l by n spring ll which hours hctween the uhutment 5 on the slide. and {L cross-pin secured to the yoke. By this menus iiny :idvnnre movement of the slide G will he rommunirntcd to the yoke, hut will he cushioned hy the spring ll. l oi' opt-r sting the slide (1 .i prefer to provide it with n. roller l which niniy he operated liy hand power, by :1 com lover, or otherwise as desired, and as the slide is advanced and 'retineted it operates to advance :uid retract the, yoke :is will he readily understood. The slide (1' nnd with it. the yoke is guided in its lorwnrd and return movement by menus ol n. pin ti depmnling l'rom the slide (l and operating in nvslot. K in the top bar ol the lu'zn-ly'et K which is mounted upon and set-tired to the hnse as shown.

The construction it will he understood is simple and ennhles me to operate the mold set-lions hoth to rlosed and opened position hy the engagement ol the nrms of the yoke with the memhcrs ol the mold sections wherehy l :im nhle to dispense with positive connections hclwecn the yoke arms and the mold sections, as will he rnnlily understood.

By preference I lock the mold by moving the yoke zirms past the dead center, hut manifestly good results may he secured by ill) moving the said arms to or near 'i ikithe dead center in the operation of thrash" tlfion, it being understood that the mold}; lock better the nearer the yoke gets to the dead center. I claim:

I 1. The combination substantially as herein described, of the mold having separable sections and provided on the outer sides thereof with inner tracks or bearings and bars secured atone end to their respective mold sections and projecting thence towards their other ends and spaced at such ends away from such sections, a yoke having its arms embracing .the mold sections and slotted for the passage of (91s track bars thereon, and having adjacent to their free ends rollers to bear upon the tracks or bearings at the outer sides of the mold sections and at the in nor sides of the track bars, a plunger operating Within the shank of the yoke and slotted longitudinally, a bolt connecting the side bars .ofthe-yoke shank and operating in the slot of the plunger, 9. springon the plun er and bearing between said bolt and a suite le stop on the plunger, and a pin projecting from the plunger and operating in the body of the yoke shank, substantially as set forth.

2". A mold having separable sections moving on a vertical pivot and provided on the outer sides thereof with inner and outer tracks or bearin s and a yoke movable radially to the mold and having its arms embracing the mold and-provided with rollers operating upon the outer and inner bearings or tracks, substantially as set forth.

8. A mold having separable sections combined with a yoke having its arms rigid with each other and embracing the mold, and

moving radial to the mold and in sliding cn-.

agement therewith to points adjacent to 61' beyond the dead center of the mold, whereby the yoke may close and lock the mold, and means on the mold for engagement by the yoke whereby it may operate to open the mold, substantially as set forth.

4. The combination with a mold having separable'sections, of a yoke having its arms rigid with each other 'and'embracin the' mold sections to operate; the some, an i havmg its shank provided with side bars spaced spars, a plunger between the said side bars of the yoke shank, and slotted longitudinally, a connecting bolt between the shank of said bars and operating in the slot of the plunger, and spring on the'plunger operating upon the connecting bolt, substantially as set forth.

5. The combination of a mold having separable sections, and a yoke movable horizonan in a direction radial to the mold and having its arms-embracing said sections and ter of the mold whereby to close the mold andr; kitinclosed osition ainst internal pressm'e,- substantia y as set orth.

'6; A'mold having separable sections and wardly in spaced relation to the tracks or bars of the mold sections, and a yoke hav' its arms embracing the mold sections an provided with means operatin upon the outer surfaces of the tracks or arings on the mold sections and the inner surfaces of the track bars on said mold sections, substantially as set forth. k 7. A mold having separable moldseqtions with each other and embracing the moldand sliding in engagement therewith to a point adjacent to or past thedead center of the mold whereby-to close and lock the mold, and a pivotal or him e connection for the mold sections arrange midway between the yoke arms substantially as described.

8. A mold having separable sections and a yoke embracing. the same and havin its arms movable in sliding engagement with the mold sections to a pointadj scent to or past the dead center thereof, the. yoke being moviablehraclially to the mold substantially as set ort outer'tracks on said sections and spaced apart, and a yoke movable radially to the mold and having its arms embracing said sections and provided with means for on ageby'it may be operated to open and clbotl the mold, substantially as setforth.

one end with its arms spaced apart and a mold between said arms and composed of two sections pivoted together midwaylbetween the yoke arms and at the base thereof, the yoke arms being engaged at theirfree ends upon the outer sides of the moldsections and movable in such engagement radially of the .mold to' points adjacent to the dead center of l the mold, all substantially as set forth.
